Gumboro Disease, also known as Infectious Bursal Disease (IBD), is a highly contagious viral illness that primarily affects young poultry, especially broilers and layers. It is caused by the Infectious Bursal Disease Virus (IBDV) and is of significant sanitary and economic importance to the poultry industry due to its immunosuppressive effects and associated production losses.
IBDV is a non-enveloped, double-stranded RNA virus belonging to the genus Avibirnavirus, family Birnaviridae. There are two main serotypes, with serotype 1 being pathogenic for chickens. Highly virulent strains can cause severe outbreaks with high mortality.
Gumboro Disease is widely distributed worldwide. Transmission occurs primarily through the fecal-oral route via contaminated feed, water, litter, and equipment. The virus exhibits high environmental resistance, which complicates its elimination and favors its persistence on poultry farms.
Clinical signs vary according to age, immune status, and the virulence of the viral strain. They may include depression, ruffled feathers, watery diarrhea, dehydration, tremors, prostration, and mortality. The characteristic lesion is the inflammation of the bursa of Fabricius, which may progress to atrophy, resulting in immunosuppression and increased susceptibility to secondary infections.
Diagnosis is based on the combination of clinical signs, anatomopathological lesions, and laboratory tests. Molecular methods, such as RT-PCR, are widely used for direct detection of the virus. Serological tests assist in evaluating the immune status of the flock and monitoring vaccination programs.
The prevention of Gumboro Disease involves rigorous biosecurity measures, sanitary control of poultry farms, and proper management of litter and equipment. Vaccination is the primary control strategy and must be planned based on maternal antibody levels and epidemiological risk, in conjunction with continuous monitoring programs.
Gumboro Disease represents one of the primary causes of immunosuppression in commercial poultry. In addition to direct losses due to mortality, the illness compromises vaccine efficacy, reduces zootechnical performance, and increases costs associated with treatments and sanitary measures, negatively impacting the profitability of poultry production.
In this context, the Bioperfectus Gumboro Disease (IBDV) rapid test serves as a practical and efficient screening tool to support sanitary surveillance in poultry farms. The use of this rapid test enables the agile detection of suspected birds directly in the field—particularly in situations involving performance drops, immunosuppression, or mortality in young poultry—allowing for the immediate adoption of containment measures, such as flock isolation, strengthening of biosecurity, and the prioritization of samples for laboratory confirmation. In this way, the rapid test acts complementarily to traditional diagnostic methods, contributing to the early identification of outbreaks, the reduction of IBDV spread, and the strengthening of Gumboro Disease control strategies.
